Abstract: FIELD: metallurgy. SUBSTANCE: method of automatic testing and complex diagnostics of state of drawing rollers and links of their drive mechanisms comprises steps of measuring current intensity values in electric drives of the drawing rollers upon casting process and testing a regularity of adjustment of the rollers along a technological axis of the plant, a value of roller barrel camber and an integrity of the rollers themselves. The method is characterized by a special order of receiving initial data for diagnostics - statistical files of current loads and by using of predetermined ways of statistical analysis of these data. At a base of primary information modules two types of standard statistical files are being formed before starting of casting process, namely a file of idling currents and a file of basic currents; statistical files of values of current intensity are also being formed at casting process. In the result of statistical procession of these data diagnostical files of current intensity change values over one revolution of each roller are being received. In these files each point of a surface of a periphery of the barrel of the roller corresponds to a mean value of current load in a given point for all primary modules of the given file. In order to perform a complex diagnostics of state of the drawing rollers two ways of statistical analysis of current load files for each roller are being used. At first spectral analysis of data of the diagnostical file is being performed in order to evaluate harmonic content of a function of current intensity change over one revolution of the roller; groups of harmonics, having a predetermined value and succession, corresponding to frequency characteristics of the roller itself and separate links of its drive, are being selected in spectrum; parameter values of each spectrum, had been received, are being compared with boundary coefficients of design "reference spectrum" and defects of the roller equipment, namely, a character and a value of camber of the roller, damages of bearing assemblies of the rollers and of reduction gears, are being evaluated according to a values of current intensity and to fluctuation degree of linear spectral coefficients of the spectrum, had been received, from the boundary coefficients of the respective "reference spectrum". At second a regularity of a adjustment of rollers along the technological axis of the plant, a change of interroller spacing, a quality of their drive mechanism tuning, an integrity of the rollers and their spindles are being diagnosed by comparison with use of amplitude-frequency analysis of current statistical files of current intensity values with standard statistical files of idling current values and basic currents. EFFECT: enhanced reliability of testing process. 1 cl, 1 dwg

Title: Elastic centralizer
Inventor: POTASHNIKOV VLADIMIR D
IPC: E21B17/10
Filed: 1995-03-22
Granted: 1997-08-27
Abstract: FIELD: drilling equipment; applicable in bottomhole assembly of drill string in drilling of oil and gas wells. SUBSTANCE: centralizer has stem, frame installed on stem with the help of radial supports and distance bushing. Frame has arched supporting strips. To limit sagging of the latter, supports are used which are made in form of rings located between end faces of radial supports and distance bushing, or in form of circular protrusions of distance bushing. Stops may be located on internal surface of supporting strips and may be removable. When drilling tool is run into well, supporting strips undergo deformation along entire length, therefore, their rigidity for bending is rather small. In drilling of curved wellbore, only central part of supporting strips undergo deformation between supports that leads to sharp rise of their bending rigidity. As a result, flexible centralizer is capable of holding the bit axis in the center of wellbore in complicated drilling conditions. EFFECT: higher efficiency. 5 dwg
